FOR FATLIQUORING AND WATERPROOFING LEATHER
Waterproofing natural and synthetic farting materials
AMARIAT AWR offers an easy production of waterproof grain and suede leather of high quality. Depending on the hide material and the leather thickness the waterproofing can be increased until! full impregnation. In order ot get a high water-resistance the tanner has to be cautious with the chemical used during the processes of beamhouse, tannery and wet Finishing. There he should avoid all materials which raise the water uptake of the leather.
AMARIAT AWR has outstanding presentation and fixing properties in a leather which is accordingly pre-treated. The neutralization has to be mild bit through the whole coss section to pH not lower than 4.5 For neutralization it is useful to use sodium sulphite, sodium formate or sodium bicarbonate, Calcium formate is unsuitable. With a leather thickness of morethan 3 mm after shaving it is recommended to extend the neutralization over night.
A retaining process with vegetable tanning materials leads to a better distribution of AMARFAT AWR and improves the waterproffing effect in the unfixed tanning agents have been throughly washed out of the leather AMARFAT AWR has to be drummed in to the leather in a short, warm f| High temperatures are not necessary. 400C, on thin leathers up to -500C thin leathers up to 500C, are recommended.
A full waterproofing of chrome leather requires about 10.0% of AMARlAT AWR.
This results in a soft learner with a mild, slightly greasy reeling.
