Instructions for use and precautions

Brylon A 400-976A resin does not contain accelerator, cobalt accelerator should be added when using, the amount of 0.5~2.0% (1% concentration).

The curing agent can be MEKP in the amount of 1.0~2.5%. It should be ensured that the curing agent is within the validity period.

The resin contains no wax.

In order to ensure the non-toxicity of fiberglass reinforced plastic products, A 400-976A is used with the following requirements for the amount of accelerator and curing agent:
Tertiary amine: ≤0.1%
Cobalt octanoate, or cobalt naphthenate: ≤0.03% Peroxide: ≤3.0%
Food-grade FRP products made with A 400-976A must be fully post-cured: 3 to 4 hours at 80°C. The product must be rinsed in hot water or steam for 1 to 4 hours. Then, rinse in hot water or steam at 80°C for 1~2 hours.
Hours. No glass fibers should be exposed on the surface of the product. The finished product must not come into direct contact with peroxide.
