Application Instructions

Preparation

Stir Part A and Part B separately to ensure uniformity before mixing.

Mixing

Weigh components in 1:1 ratio and mix thoroughly for homogeneous consistency.

Defoaming

Natural Defoaming: Allow 20-30 minutes for air bubble release
Vacuum Defoaming: 5-10 minutes at -0.1 MPa vacuum

Potting

Apply to clean, dry surfaces while mixture maintains good flowability.

Curing

Room temperature or heat accelerated curing available. Higher temperatures reduce curing time.

Packaging & Storage

Packaging: 5290RA9 20kg/barrel, 5295RB9 20kg/barrel

Storage: 8-28°C in cool, dry location. 6 month shelf life when properly stored.

Safety Information

Store in sealed containers away from children. Avoid contact with N, P, S organic compounds and Sn, Pb, Hg, As ionic compounds which may inhibit curing. Consult MSDS for complete safety details.
