Anti set-off powder S5WL
Anti set-off powders of the S5WL range are organic, vegetable based products made of native starch. The single particles have a round and soft shape. The regular particle size distribution and the character of the powder particles support easy and reliable handling. The S5WL range is additionally surface treated by a special process. They will get by this a hydrophobic, water-repellent property. Hence
S5WL powders are especially suitable for the finishing of prints with water-based varnishes. Anti set-off powders of the S5WL range are insensitive against ordinary humidity. They are stable in storage. They are neither soluble in water nor in alcohol.
The S5WL range is already available in the graduations 15, 20, 30 and 45 for a long time. Two especially low-dust powder types S5WL/16 and S5WL/22 complete the well known series.
A further intensive particle selection reduces the portion of particles smaller 10 microns effectively.
Anti set-off powders of the S5WL range are constantly controlled and correspond – with exception of the finest type S5/15 – to the German industry-wide agreement of low-dust anti set-off spray powders.
