Thermoplastic Acrylic Resin

Thermoplastic Acrylic Resin System

Product Name: TPA 60%
Delivery Form: 60 ±2% solids in Xylene
System Type: Thermoplastic acrylic copolymer resin for exterior coatings and concrete applications

Product Description

Epoxite TPA 60% is a high-performance thermoplastic acrylic resin solution designed for outdoor protective coatings, especially on concrete surfaces and construction substrates. With a solid content of 60% in xylene, this low-odour system offers exceptional weather resistance, gloss retention, and pigment compatibility. Its inherent flexibility, hardness, and non-yellowing nature make it a preferred binder for decorative, metallic, and protective finishes exposed to harsh environments.

Key Features

• Excellent gloss and long-term gloss retention

• High yellowing resistance under UV exposure

• Flexible yet hard film formation

• Low odour and solvent-borne formulation

• Ideal pigment dispersion and plasticizer resistance

• Compatible with multiple common solvents

Applications

TPA-696 is ideal for a wide range of applications in construction and coatings, including:

Concrete Coatings & Sealers
Used as a binder in durable exterior coatings for concrete surfaces like pavements, walkways, and exterior walls where flexibility, UV resistance, and weatherability are critical.

Metallic Paints & Decorative Finishes
Works excellently as a binder for metallic finishes, thanks to its superior pigment dispersion and high-gloss characteristics.

UV-Resistant Protective Layers
Ideal for topcoats where long-term yellowing resistance and gloss retention are essential in sunny or harsh outdoor conditions.

Processing & Application Guidelines

Recommended Application Methods

• Apply via brush, roller, or spray system

• Substrate should be clean, dry, and free from oil or contaminants

• Use appropriate solvent dilution if required for application viscosity adjustment
  
  

Curing Characteristics

• Being thermoplastic, the coating forms a film via solvent evaporation

• No chemical curing (crosslinking) is required

• Typical drying time: Surface dry in 10–15 minutes; hard dry in 2–4 hours (depending on temperature and airflow)
  
  

Storage & Shelf Life

• Store in tightly sealed containers away from heat and direct sunlight

• Ideal storage temperature: 5°C – 30°C

• Shelf life: 12 months from date of manufacture under standard storage conditions
  
  

Safety

• Flammable liquid; keep away from sparks, heat, and open flames

• Use only in well-ventilated areas

• Avoid contact with eyes and skin – use appropriate PPE (gloves, goggles)

• In case of contact, wash with soap and water or seek medical attention

• Refer to MSDS for full safety precautions
