WJG-421 Metal Roof Repairing Special Fluorocarbon Film Butyl Rubber Self-adhesive Waterproof Roll

It is a high-performance polymer waterproof membrane specifically designed for metal roofs. It consists of a PVDF composite film as a surface enhancing material, covered with a butyl rubber self-adhesive layer and a separating layer.

WJG-422 Aerogel Reflective Heat Insulation Waterproof Roll Material

It is a rollable sheet-like waterproof material that mainly provides waterproof function and also heat insulation. It is composed of PET reflective aluminum film + aerogel insulation layer + butyl rubber self-adhesive layer + isolation film, etc.

WJG-431 Polyurea Grouting Material

Polyurea grouting fluid is a high-performance, single-component polymer grouting material made from polyurea emulsion through scientific processing.

WJG-432 cement-based grouting material

It is a dry-mixed material with cement as the basic material, a proper amount of fine aggregate, and a small amount of concrete admixture and other materials. After mixing with water, it has high fluidity, early strength, high strength, and micro-expansion properties.

WJG-433 inorganic salt grouting material

It is a two-component or multi-component homogeneous liquid grouting material made mainly from an aqueous solution of acrylate monomers with an appropriate amount of crosslinking agent, accelerator, initiator, water and/or modifier added.

WJG-434 epoxy resin grouting material

It is a material mainly composed of epoxy resin, with a certain proportion of curing agent, diluent, toughening agent, etc., mixed together.

WJG-435 polyurethane grouting material

WJG-436 silane-modified polyether grouting material

A homogeneous liquid composed primarily of a resin synthesized from the polymerization of silane and polyether polyol, along with mineral fillers and additives. This material is a grouting material that forms an elastomer through reaction with water.

Polyurethane grouting material for emergency rescue in tunnels, subways, and galleries

It is a functional material that can quickly stop water leakage. It utilizes the characteristic of isocyanate groups in polyurethane prepolymers reacting with water to release carbon dioxide. When the sealant is injected into the leaking area, the material reacts rapidly with water to form a solidified body, thereby reducing or stopping water leakage.
