Helpa RDP

Description:
Synthetic tanning agent with special dispersing properties.

Chemical nature:
Combination of aromatic sulphonic acids and other dispersing products.

Characteristical features:
Appearance: Powderish solid Nature: Anionic Active materia: >88% PH Value (1:10): 7.5 +-0.7 Colour: Beige VOC: 0%

Properties:
Helpa RDP is a product that improves the penetration capacity of retanning and colouring products, allowing that both can do this evenly. This product gives better equalization and distribution on the items. Helpa RDP is easily water-soluble. It also accelerates the penetration of vegetable tanning agents and other anionic products, reducing the astringent action when penetrating into the leather. Due to the neutralization produced at the beginning of the penetration into the leather, before the retanning of chrome tanned leathers, a relaxed and even penetration of the later added retanning and colouring agents is produced. The outcome is a more equalized and intense coloured crust where the neck veins are less marked than with a normal dispersing agent. The product does not noticeably discolour the dyes.

Storage capacity:
The product can be stored in its well closed container, in a well ventilated place at temperatures between +5 and +38ºC. In its sealed container it lasts 6 months.

Application:
Helpa RDP gives to the grain a very acceptable pore fineness because it does not over-charge it and it produces low reactivity on the grain. The grain stays elastic even applying retanning agents with high astringency. In a normal retanning process, normally around 3% of Helpa RDP is used, 15 or 20 minutes before adding the main retanning package.
