Detailed Product Description

HLDJ801 HUALI HOT MELT BUTYL RUBBER, a single-component sealant without flux, takes imported butyl rubber and polyisobutylene as its basic materials. It gives outstanding seal ability and adhesion to aluminum, glass and stainless steel, and has properties of non-split, non-hardening, as well as excellent resistance to heat and water immersion, all of which makes it an ideal choice for the first sealing of insulating glass.

The product is applied for the first sealing of insulating glass, and can also be used together with two-component Thiokol rubber, two-component elastic silicon sealant, two-component polyurethane sealant and single-component hot melt. Certified by National Glass Testing Center, the dual-sealing insulating glass made with the HLDJ-801 HOT MELT BUTYL RUBBER is able to fulfill all the international requirements.

Make clean and dry the surface of glass and aluminum that are to be adhered to, remove dust and greasy filth from them. Extrude the product with special extruder for hot melt butyl and smear it homogenously on the glass and aluminum. Ideal extruding temperature is expected to be 125ºC135ºC,  and ambient temperature no lower than 5ºC.
