TECHNICAL DATA SHEET
CHEMITAC A400 + CHEMITAC H400
DESCRIPTION:
Chemitac A400 is a two-components base on polychloroprene rubber, room temperature adhesive
that, when catalyzed with the appropriate amount of Chemitac H400, yields high strength
adhesions. Chemitac A400 is used to bond natural rubber, neoprene rubber, SBR, EPDM…
Chemitac A400 is ideal for use in lining installations, when bonding rubber to rubber, rubber to
fabric, rubber to steel, rubber to concrete, fiberglass, and urethane, as well as the splicing and
repair of fabric conveyor belting. Repair to existing rubber lined vessels and rubber components are
also recommended using this system.
Chemitac A400 + Chemitac H400 are a heavy metals free product.
TYPICAL PHYSICAL CHARACTERISTICS:
Appearance : Black.
Diluents : Ethyl Acetate
Application Temp : 5 to 45oC (41o to 113o F)
Shelf life : 24 months (closed can below 25oC).
Mixing Instructions:
Chemitac A400 system is comprised of cement and hardener in the ratio of 700 grams of Chemitac
A400 adhesive to 30 grams of Chemitac H400 hardener. These two components must be
thoroughly mixed (stirred). The mixed portion should be used between 2-3 hours.
CHEMICAL COMPOSITION:
Rubbers in solvents.
GENERAL CONDITIONS HOW TO USE THE ADHESIVE:
Before any sandblasting, application of primer, adhesives… the substrate must be at least 10oC
(50oF) with a maximum temperature of 40 to 45 oC (104-113 oF).
The relative humidity should not exceed 80 % during the entire lining procedure.
The substrate temperature must be a minimum of 5 degrees higher than that of the dew point. It is
important that these conditions are recorded prior to start and at three hour intervals thereafter.
