Camcure

Whatsapp Order

Camcure is a specialized epoxy hardener designed to be used in conjunction with epoxy resins to facilitate curing, improve mechanical strength, and enhance chemical resistance. It typically appears as a clear to pale yellow liquid with low viscosity, enabling easy mixing with resin systems. This hardener is widely used in coatings, adhesives, composites, and industrial applications requiring durable, tough, and chemically resistant cured products. Camcure 9115X70 promotes rapid curing at ambient or elevated temperatures and offers excellent adhesion to a variety of substrates including metals, plastics, and concrete.

Camcure (Hardener)

Primary Uses

Industrial Coatings

Used as a curing agent in epoxy coatings for metal protection, machinery, and structural steel to provide corrosion resistance and surface hardness.
Applied in flooring systems where chemical resistance and mechanical durability are critical, such as in factories and warehouses.

Adhesives and Sealants

Serves as a hardener in two-component epoxy adhesives offering strong bonding for metals, plastics, wood, and composites.
Used in sealants for structural and electronic assembly applications requiring high chemical and heat resistance.

Composites and Laminates

Employed as a curing agent in the production of composite materials used in automotive, aerospace, and marine industries to enhance strength and durability.

Electrical and Electronics

Used in encapsulation and potting compounds to protect sensitive electronic components from moisture, dust, and mechanical stress.

Secondary Uses

Repair and Maintenance

Used in epoxy repair mortars and patching compounds for concrete and metal surfaces.
Employed in tooling and mold-making applications to cure epoxy molds with high dimensional stability.

Art and Craft

Used by artists and craftsmen for epoxy resin art pieces, coatings, and jewelry where clarity and hardness are desired.
