4000 Series - Water-borne Acrylic Binders

A range of high performance acrylic resins for water-based systems.

Products

DeCAL 4002 - Thermosetting Acrylic Emulsions

DeCAL 4002, 4003 and 4005 are versatile high performance anionic self crosslinking polymers for the production of high performance finishes across a variety of industries.

The chemical nature of these polymers means that high temperature curing is required to achieve the maximum performance benefits. Treated substrates should be cured at 150°C for up to two minutes. The use of an acid catalyst such as p-toluene sulphonic acid can be used with DeCAL 4003 and 4005 to reduce the curing temperature and accelerate the curing response.


Applications
These products can be used to produce highly resistant finishes on surfaces including wood, paper board and PVC, and in the textiles industries to impart finishes with properties ranging from slightly crisp to very stiff with minimal chalking effect.

Benefits

  • Compatible with most anionic and non-ionic textile and coating auxiliaries including antifoams, wetting agents, coalescing solvents and thickeners.
  • In textiles, produces films with minimal effect on the colour of fabrics.
  • Very resistant to washing and dry cleaning, with minimal chalking effect.
  • Non-toxic.

DeCAL 4201

DeCAL 4201 is an acrylic binder which exists as an alkali soluble carboxylated copolymer emulsion but can also be supplied in its neutralized varnish form as DeCAL 4202.

DeCAL 4201 tends to swell considerably in the early stages of neutralisation. As a result it is recommended that the product be prediluted to with water prior to any neutralisation and then left to stabilise for several hours afterwards before use. DeCAL 4202 is supplied pre-neutralised with the commonly used Monoethanolamine(MEA).

Applications

ideally suited for use in waterbased flexographic inks for paper and corrugated board.

Benefits

  • Excellent machine stability/resolubility.
  • High viscosity/pH stability.
  • Possesses favourable viscosity/dilution curves.
  • Excellent pigment wetting characteristics.
