| Mitsui Chemicals is a leader in the development
of high performance laminates and adhesives for food and non-food applications
where high performance, fast curing and chemical resistance are needed. There
are solvent based and solvent free grades of TAKELAC™, used for different
types of retort packaging
applications as well as for solar cell backing and PDP mesh filter.
TAKELAC A525S
The solvent based adhesive TAKELAC A-525S, is a polyester polyol with a low coating
weight of 3.0-4.0g/m2. It is bis-phenol A and organotin compound free. TAKELAC
A-525S is used in conjunction with the co-reactant, TAKENATE™ A-50, an isocyanate
terminated hardener, to produce a two-component polyurethane adhesive used for
dry lamination, such as PET/Al/CPP, PET/Ny/Al/CPP, PET/Al/Ny/CPP, PET/Ny/CPP or
Ny/CPP.

TAKELAC is a fast curing material taking approximately 3 days to fully cure
for retort packaging at a temperature of 104°F or 40°C, which is lower
than that of other materials with a 5 day curing period at 122°F or 50°C.
TAKELAC A-525S/TAKENATE can be safely used for aluminum retort pouches and microwavable
retort pouches in compliance with the Food and Drug Administration.
TAKELAC A-670A
Solvent free adhesive TAKELAC A-670A, is a polyester polyol, offering several
of the same benefits as the solvent based adhesive. The material is bis-phenol
A and organotin compound free, with a low coating temperature of 122-140°F
or 50-60° C.
TAKELAC A-670A is used with the hardener TAKENATE A-670B, to be used in food
packaging for dry food, boiled pouch, standing pouch, aluminum retort packaging
applications.
TAKELAC is manufactured to meet the highest quality and environmental standards.
All grades of the material comply with the latest complex Food and Drug Administration
(FDA) requirements and regulations for retort packaging. The solvent based grade
A-525S is approved by FDA 21 CFP 177, 1390 and the solvent free grade A-670A/A-670B
is pending FDA approval.
TAKELAC A-1150
TAKELAC A-1150 is a solvent based polyurethane adhesive used for PDP mesh filter.
TAKELAC A-1150 is used with the hardener TAKENATE A-3070.
