Emulsion Hardeners

KIWOSET A-WR

Hardener for chemically curable screen printing and textile printing emulsions

KIWOSET A-WR is an acidic, aqueous solution for the chemical hardening of photoemulsions. It can easily be distributed and forms an evenly spread film which enables a homogeneous curing result. KIWOSET A-WR is especially suitable for textile and ceramic printing. It can also be used to increase the chemical and mechanical stability of screen or textile printing stencils. Photoemulsions hardened with KIWOSET A-WR are difficult to decoat or even undecoatable due to the achieved high resistances.

KIWOSET E-WR

Hardener for chemically curable screen printing and textile printing emulsions

KIWOSET E-WR is an acidic, aqueous solution for the chemical hardening of photoemulsions. It can easily be distributed and forms an evenly spread film which enables a homogeneous curing result. Especially suitable for textile printing screens with which alkaline or acidic media (vat caustics) are printed. In some cases, it is recommended to make trials with the respective emulsion beforehand. In particular cases, KIWOSET E-WR can be used reduced with water in a ratio of 1:1 to 1:3. In general, photoemulsions treated with KIWOSET E-WR are very difficult to decoat or even undecoatable due to the achieved high resistances.

KIWOSET HP

For post-hardening of direct Screens

KIWOSET HP is used to increase the water resistance of photoemulsions which are already waterproofed. Even waterproof emulsions contain water soluble components, so an absolute waterresistance without post-treatment is impossible KIWOSET HP gives the screen a higher resistance butmakes decoating more difficult.With many solvent resistant photoemulsions their water resistance can be increased after treatment withKIWOSET HP. Short print runs with water based printing inks and adhesives (e.g. KIWOPRINT D series)are possible. At high air humidity, which can influence the printing resistance of a screen, a posttreatmentwith KIWOSET HP is necessary.KIWOSET HP can be used on polyester, nylon and metal meshes. It is not corrosive.

KIWOSET K-T

Hardener for chemically curable screen printing and textile printing emulsions

KIWOSET K-T is an acidic, aqueous solution for the chemical hardening of screen printing and textileprinting emulsions (refer to the technical data sheets of the respective emulsions). It can easily bedistributed using a brush and forms an evenly spread film which enables a homogeneous curing result.No residue remains in the open areas after evaporation of the hardener.
