Hybrid vinylester chemical anchor: the complete guide

Everything you need to know about the hybrid vinylester chemical anchor — from the principle, through installation, to the largest projects. ADIT CHEMFIX200 has been the best-selling chemical anchor in Israel over the past decade, and in every head-to-head comparison against competitors it has come out on top. This guide was written by the experts at Adit Ltd., the largest chemical-anchor company in Israel.

What is a hybrid vinylester chemical anchor and how does it work?

A hybrid vinylester chemical anchor is a two-component chemical adhesive that combines the best of two systems: a highly reactive vinylester base together with advanced hybridization additives.

The result is a chemical anchor offering exceptionally high performance, fast cure time and excellent durability in tough field conditions — at a competitive price compared to pure epoxy. When the two components are mixed (inside the mixer nozzle), a rapid chemical reaction begins, forming a strong polymer structure that bonds firmly to the base material.

Why “hybrid”?

The advanced formula combines the fast cure of vinylester with enhanced resistance to moisture and chemicals. Unlike ordinary polyester, the hybrid formula of CHEMFIX200 allows the chemical anchor to be used in wet concrete and ensures a durable hold over time. This is an advantage that extensive testing in Israel has proven time and again to be unrivaled in this category of chemical anchors.

Chemical anchor installation steps — recommended workflow

  1. Drilling — drill to the diameter and depth specified in the manufacturer’s table.
  2. Cleaning the hole — use a cleaning brush and blow out the dust (hand pump or compressed air). This is a critical step for optimal holding of the chemical anchor!
  3. Injecting the adhesive — fill the hole from the bottom upward (about 2/3 of the hole depth) using a dedicated dispenser and static mixer. Be sure to inject a small waste bead on the side before injecting into the hole, to confirm even mixing of the components (uniform color).
  4. Inserting the anchor — insert the threaded rod / rebar while slightly rotating it to distribute the material around the full circumference of the hole and prevent air bubbles.
  5. Cure time — wait for the material to cure. Hybrid vinylester has an especially fast cure time: it can be loaded after a relatively short time depending on ambient temperature (per the manufacturer’s tables).

The best-selling chemical anchor in Israel — and not by chance

Over the past decade, ADIT CHEMFIX200 has cemented its position as the best-selling chemical anchor in Israel. Behind this figure lies something far more solid than mere marketing: very large quantities of laboratory and field tests conducted in Israel, including head-to-head tests against competing chemical-anchor products — in all of which CHEMFIX200 came out on top.

The tests examined resistance at extreme temperatures, holding in wet concrete, chemical-anchor performance in cracked concrete, cure times in cold conditions and more — and in every key parameter the product recorded superior results. This is why structural engineers, contractors and infrastructure companies throughout the country keep choosing it project after project.

Advantages of the hybrid vinylester chemical anchor (CHEMFIX200)

The market offers several types of chemical-anchor systems: polyester, epoxy and vinylester. The advanced hybrid vinylester chemical anchor offers a unique combination of advantages that makes it the most balanced and competitive solution on the market:

  • Fast cure: reaches full strength significantly faster than pure epoxy, shortening work times and lowering costs on large projects.
  • Moisture and wet-concrete resistance: unlike ordinary polyester, the formula is not affected by water and allows work in humid environments and even in wet drill holes.
  • High holding strength: high tensile and shear load values suitable for demanding engineering projects.
  • Temperature stability: retains its properties over a wide temperature range, including work in extreme heat and cold.
  • Competitive price: a chemical anchor that delivers high performance at a lower cost than pure epoxy — an ideal economical solution for very large projects.
  • Approvals and standards: meets the requirements of the European standard (ETA) and is recognized by structural engineers. The adhesive is also approved for cracked and non-cracked concrete and for seismic categories C1-C2.
  • Safer work environment: the hybrid formula (usually Styrene Free) reduces pungent odors and chemical exposure compared with classic vinylester, allowing work in enclosed spaces.

Common applications and major projects

ADIT CHEMFIX200 has proven itself in the field on the most complex and demanding projects in Israel and worldwide. A combination of fast cure, strong chemical hold and durability has made it the first choice on projects such as:

  • Ports (including underwater anchoring and salt-water / pressure environments)
  • Tunnels and bridges
  • High-rise buildings and luxury towers
  • Malls and underground parking garages
  • Factories and public infrastructure

The ability to work quickly without compromising strength makes hybrid vinylester the preferred solution when schedules are tight.

Frequently asked questions

What is the difference between a hybrid vinylester chemical anchor and ordinary polyester?
Ordinary polyester is the cheapest solution on the market, but its performance is significantly lower: it tends to creep under load, is sensitive to moisture, and is not suitable for industrial environments or high loads. By contrast, a hybrid vinylester chemical anchor (such as CHEMFIX200) offers excellent moisture resistance, far higher holding strength and a fast cure time — a significant performance gap proven in the field.
What is the difference between hybrid vinylester and pure epoxy?
Pure epoxy offers the highest holding values (especially in very deep drill holes or large diameters), but is characterized by a relatively long cure time (sometimes 24 hours) and a high price. Hybrid vinylester delivers very high performance suitable for 95% of projects, but with a significant advantage in cure time (minutes to a few hours) and a more economical cost.
How long does the chemical anchor take to harden before it can be loaded?
Cure time depends on the ambient and concrete temperature. One of CHEMFIX200’s standout advantages is its fast cure. At an ideal temperature (about 20°C) the anchor can be loaded after roughly an hour (versus a full day for epoxy). In high heat, curing is significantly accelerated; in cold it is extended. Always follow the exact cure tables the manufacturer provides for each temperature.
Can a chemical anchor be used in wet concrete?
Yes! Unlike simple polyester anchors that are damaged by water, an advanced chemical anchor such as ADIT CHEMFIX200 is officially approved for use in wet concrete. The hybrid formula is designed so the chemical reaction proceeds correctly and creates a strong hold even when there is moisture or water in the hole.
What is the correct drill-hole size for chemical anchoring?
The hole size must precisely match the diameter of the threaded rod or rebar. As a rule of thumb, the hole should be 2 to 4 mm larger than the rod diameter (for example, a 10 mm rod usually requires a 12 mm hole). Incorrect drilling (too wide or too narrow) can seriously impair the anchor’s durability. Rely on the manufacturer’s recommended drill and depth table.
Is a chemical anchor suitable for work in cracked concrete?
Absolutely. A quality chemical anchor (such as CHEMFIX200) holds a specific ETA approval for “cracked concrete.” This means the material is flexible and strong enough to cope with the micro-movements and crack expansion in concrete under load. Make sure the version you have actually carries this approval, since not every chemical anchor is approved for cracked concrete.
Under what conditions should chemical-anchor cartridges be stored?
To preserve the shelf life and chemical efficacy of the material, store chemical-anchor cartridges in a cool, dry and shaded place (usually at temperatures of 5°C to 25°C). Prolonged exposure to direct sunlight or to high temperatures in a vehicle will cause the material to spoil and harden inside the cartridge before use.
Is it mandatory to use a cleaning brush to clean the hole?
Unequivocally yes! This is one of the most common installation mistakes. If a metal brush and air pump are not used to clean the drilling dust out of the hole, the chemical anchor will bond to the dust instead of to the solid concrete walls, which can reduce holding strength by tens of percent and cause the anchor to fail.
What is a hybrid vinylester adhesive?
A hybrid adhesive combines the advantages of epoxy (high strength) and polyester (fast setting). The result: a much shorter setting time than pure epoxy, with high load values and approval for cracked concrete and seismic conditions.
What is the difference between Chemfix200 and Chemfix100?
Chemfix100 is a pure epoxy — maximum pull-out strength and approval for Shock loads. Chemfix200 is a hybrid — it sets faster and additionally carries American ESR approval, a masonry approval and a potable-water approval. For projects with especially heavy loads — Chemfix100. For breadth of approvals and fast work — Chemfix200.
Can it be used in hollow blocks?
Yes — it has a separate ETA approval for masonry. Anchoring in a hollow block also requires a sleeve or mesh, which prevents the adhesive from flowing into the cavity.
What is WRAS approval?
WRAS is the British approval for contact with potable water. It means Chemfix200 can be used for anchoring inside water reservoirs, main water lines and potable-water facilities, with no risk of contamination.
