Key Features & Benefits

Environmentally Friendly: Formulated in compliance with GB 33372-2020, meeting the latest environmental standards for volatile organic compound emissions in adhesives. Free of restricted heavy metals.
Superior Construction Performance: Easy to apply by brush, dip, or spray methods with excellent wetting and coverage on various substrate surfaces.
Pre-Baking Resistance: Maintains adhesive integrity during pre-baking processes, ensuring consistent bonding strength throughout manufacturing.
High Temperature Resistance: Withstands elevated temperatures encountered during vulcanization and in-service operation without degradation.
Excellent Fatigue Resistance: Provides durable, long-lasting bonds that resist failure under dynamic loading and cyclic stress conditions.
Anti-Corrosion Performance: Protects bonded metal surfaces from environmental corrosion, extending the service life of bonded assemblies.
Anti-Deformation Performance: Maintains bond integrity under mechanical stress and substrate deformation.
Outstanding Weather Resistance: Resists heat aging, water immersion, solvent exposure, oil contact, and salt spray conditions.

Application Range

815GB primer is suitable for use as both a one-coat adhesive and as a primer in a two-coat system (primer + cover coat). It demonstrates excellent adhesion to a broad spectrum of substrates:

Category	Compatible Substrates
Metals	Carbon steel, stainless steel, aluminum, copper, zinc, titanium, magnesium, lead, and various alloys
Non-Metals	Nylon, fiberglass, PTFE, rubber, plastic, fabric fibers, glass, ceramics

Application Instructions

Surface Preparation: Ensure substrate surfaces are clean, dry, and free from oil, grease, rust, and other contaminants. For metals, grit blasting or chemical treatment is recommended.
Mixing: Stir thoroughly before use to ensure uniform dispersion of solids.
Application: Apply a thin, uniform coat by brush, dip, or spray method.
Drying: Allow to dry at room temperature until solvent has evaporated. Force drying at 60-80°C may be used to accelerate the process.
Cover Coat: For optimal performance in demanding applications, follow with a compatible cover coat adhesive (such as 829GB) before rubber vulcanization.

⚠ Safety Note: Contains organic solvents. Use in well-ventilated areas. Keep away from heat, sparks, and open flames. Wear appropriate protective equipment. Refer to the Safety Data Sheet (SDS) before use.
