Applications
Crystic® VE 671-03 PA is recommended for:
Chemical containment equipment
Tanks, vessels, pipes, ducting, and liningsIndustrial composite structures
Components exposed to corrosive or high-temperature environmentsMarine & automotive components
Where strength, durability, and chemical resistance are criticalVacuum infusion & closed-mould laminates
Infrastructure and process equipment
Requiring long-term resistance to aggressive service conditions
Resin Properties (Uncured)
Appearance: Yellowish, clear
Viscosity: ~175 mPa·s (Brookfield Spindle 3, 60 rpm @ 25°C)
Gel Time @ 25°C:
~35 min with 2% Butanox® LPT
~110 min with 0.06% Acetyl Acetone + 2% Trigonox® 239
Storage Stability: Up to 6 months at ≤20°C
Mechanical & Thermal Properties (Cured)
(Post cure applied)
Barcol Hardness: ~40
Heat Deflection Temperature (HDT): ~100°C
Tensile Strength: ~80 MPa
Tensile Modulus: ~3.4 GPa
Flexural Strength: ~130 MPa
Elongation at Break: ~4.5%
These properties make VE 671-03 PA particularly suitable for structural laminates requiring both toughness and chemical durability
Processing & Handling
Crystic® VE 671-03 PA is pre-accelerated and designed for cold curing. It requires only the addition of a low-reactivity MEKP catalyst, such as Butanox® LPT, to initiate cure.
Important: Catalyst and accelerator must never be mixed directly together.
Post curing is recommended to achieve optimum chemical, water, and heat resistance prior to placing parts into service.
