PU-30 Low Modulus Construction Polyurethane Sealant
PU-30 Low Modulus Construction Polyurethane Sealant
PU-30 is a one-component, moisture-curing polyurethane joint sealant designed to seal expansion, control, and connection joints in construction. Its "low modulus" formulation means it offers high elasticity and stretches easily under stress without putting undue pressure on the joint edges

EP 3209A/B Two Component Black Epoxy Structural Adhesive
Product description
EP 3209A/B Epoxy adhesive is a room temperature/heat curing resin adhesive. This two-component bonding adhesive is designed for metal bonding, bonding of cube or SMC fiberglass parts, aluminum honeycomb plate splicing and magnetic steel tile bonding of motor products, ceramic film component sealing, internal structure bonding of lithium battery module, soft magnetic unit potting, high temperature sensor potting, etc.
EP 3209A/B epoxy adhesive can cure in both room temperature and heating environment. After thoroughly mixing component A and component B at 100:50 (weight ratio), the product cures within a certain period of time to form protection.
The cured glue has the following properties:
Resistance to moisture, dirt, and other atmospheric components
High strength, excellent adhesion
Good pollution resistance, low surface pretreatment requirements
No solvent, no curing byproducts
Excellent high and low temperature resistance, -50℃-180℃
Transformer oil resistance, low attenuation
It has good adhesion to glass fiber cloth, aluminum and plastic, aluminum and aluminum and steel plate
