Tools Typically Required:
Wear gloves and wash hands after use.
Safety Precautions:
Use in a well-ventilated area. Protect work area before and during use. Wear gloves (nitrile gloves recommended) and wash hands after use.
Preparation:
Protect work area. Surfaces to be glued must be sound, clean, dry (see Application below) and free of grease, dust, old adhesive residue, paint
and other contaminants such as plasticizers and mold release agents. Remove contaminants with alcohol or acetone (tests surfaces for
compatibility before). For improved adhesion, lightly sand very smooth or glossy surfaces and clean thoroughly. Pre-fit all materials before applying
adhesive. When bonding two non-porous surfaces, dampen surfaces lightly before applying adhesive. Mask off the adjacent areas with tape
before gluing if necessary. To open, rotate cap counterclockwise.
Application:
Apply a thin layer of adhesive to one surface. Bond parts immediately after applying the adhesive and hold or clamp parts together (before skin
formation) for at least 30 minutes. For best results allow 24 hours cure before subjecting to stress. Unlike other adhesives, high pressure during
curing is not necessary. Very porous materials will require a thicker layer of adhesive and application to both surfaces may be required.
