The difference between structural glue, weatherproof glue and sealant

The difference between structural glue, weatherproof glue and sealant

1. Weather-resistant Adhesive: used for weather-resistant sealing of various glass curtain walls; used for weather-resistant sealing of metal (aluminum plate) and enamel curtain walls, and sealing of roof construction joints.

2. Structural Adhesive: mainly used for reinforcement, anchoring, bonding, repairing, etc. of components; such as bonding steel, bonding carbon fiber, planting reinforcement, crack reinforcement, sealing, hole repair, road stud bonding, surface protection, concrete bonding, etc. .

3. Sealant: It is an adhesive used to fill the gaps in the configuration to play a sealing role. It has the functions of anti-leakage, waterproof, anti-vibration, sound insulation and heat insulation.

Different manufacturing principles

1. Weather-resistant glue: Use a glue gun to squeeze the glue from the sealant cylinder into the seam that needs to be sealed. The sealant absorbs moisture in the air at room temperature.

2. Structural rubber: It can be easily squeezed out under wide temperature conditions and cured into excellent, durable, high-modulus and high-elasticity silicone rubber by relying on moisture in the air.

3. Sealant: use dry or non-dry viscous materials such as asphalt, natural resin or synthetic resin, natural rubber or synthetic rubber as the base material, with inertness such as talc, clay, carbon black, titanium dioxide and asbestos Fillers are made by adding plasticizers, solvents, curing agents, accelerators, etc.
