Introduction
Introduction
This is non pigmented clear lacquer based on specially design modified resin cured with hardener. This is special product for aluminum formwork.
Scope
It provides excellent protection to Aluminum Formwork. It forms a durable air
drying, film over the surface. The product possesses good flexibility,
adhesion,
water and chemical resistance.
The basic element of Formwork technology is the panel which is a framework of extruded aluminum sections, welded to an aluminum sheet.
The panels are made from a high strength aluminum alloy, with the face or contact surface of the panel, from 4mm thick plate, which is welded to
a framework of specially designed extruded sections, to form a robust component.
Basically cement concrete material is alkaline with high pH 12 to 13. This is react on aluminum surface, at the time of concrete making process we are
adding
water it is react with tricalcium silicate (present in cement) it produce calcium silicate hydrate & amp calcium hydroxide.
The calcium hydroxide reacts with aluminum form Tricalcium Aluminates (calcium oxalate or tricalcim aluminates it does not occur in nature, but is an
important mineral pahse in Portland cement.)
at time of reaction release hydrogen gas then started corrosion on aluminum surface.
Chemical Resistance
| Exposure | Splash and Spillage | Mild Fumes/Outdoor Resistance |
|---|---|---|
| Acids | Good | Good |
| Alkalis | Good | Very Good |
| Solvents | Good | Very Good |
| Salt | Good | Very Good |
| Water | Good | Very Good |
Application
Stir the base thoroughly; Mix 4 parts of base and 1 part of catalyst by volume to uniform consistency. Let the mixture mature for 15 minutes.
Stir it again before and during application.

Challenges & Solutions
Challenges
- Surface Abrasion and Damage During Repeated Use
Problem: Aluminium formwork systems are reused many times on construction sites, often exposed to rough handling, abrasion, and impact—leading to surface damage, reduced lifespan, and high maintenance costs. - Concrete Adhesion to Aluminium Surfaces
Problem: Without proper surface protection, concrete can adhere to aluminium panels, making demoulding difficult and damaging the finish of both the formwork and the concrete surface. - Corrosion and Oxidation of Aluminium
Problem: Aluminium formwork exposed to moisture, cement slurry, and construction chemicals can oxidize or corrode over time, especially in humid or coastal environments. - Frequent Reapplication of Temporary Coatings
Problem: Conventional coatings or oils used on aluminium formwork often wear off quickly and require reapplication after every few uses, adding to labor and operational costs. - Maintaining a Clean, Professional Appearance
Problem: Dirty, stained, or discoloured formwork can affect the quality of the final concrete finish and reflect poorly on project execution.
Solutions
- Constro-067® Lacquer forms a tough, protective film over aluminium surfaces, significantly improving resistance to scratches, wear, and mechanical damage. This helps extend the life of the formwork and reduces the need for frequent repair or refinishing.
- Constro-067® provides a smooth, non-stick coating that acts as a release layer, preventing concrete adhesion. This ensures easy, clean demoulding and protects both the aluminium and the poured surface finish.
- Constro-067® Lacquer offers excellent resistance to moisture, alkalis, and chemicals commonly found on construction sites. It creates a protective seal that shields aluminium from corrosion, increasing durability and performance.
- Constro-067® is a high-performance lacquer with long-lasting durability. One application provides extended protection through multiple reuse cycles, reducing downtime and material consumption on site.
- Constro-067® delivers a clear, smooth, and glossy finish that repels dirt and stains. It helps maintain the clean appearance of formwork panels, which also enhances the surface finish of concrete structures.
