LITEX S 9070 is a binder for technical textiles and glass fibre. LITEX S 9070 is an aqueous, anionic dispersion of a carboxylated self-crosslinking butadiene styrene copolymer containing a non-staining antioxidant.

PLEXTOL X 4855: binder for PSA. PLEXTOL X 4855 is an aqueous emulsion of a thermoplastic acrylic polymer.

PLEXTOL PR 3500: deep penetrating primer. PLEXTOL PR 3500 is an aqueous dispersion acrylic copolymer with an ultrafine particle size. It is particularly recommended for formulating penetrative primers for porous substrates. The emulsion can also be used in formulating products for use on wood, in particular wood stains.

ALCOTEX WD100 is a suspending agent for vinyl chloride polymerisation. ALCOTEX WD100 is an aqueous solution of a 43% hydrolysed polyvinyl alcohol. It has been specifically developed by Synthomer Ltd as a secondary suspending agent for vinyl chloride polymerisation. Infinitely dilutable in water, and with an extremely low methanol content, ALCOTEX WD100 offers increased PVC resin porosity and reduced levels of gels or ‘fish eyes’ when compared to traditional products.In optimised recipes, improvements can be obtained in the porosity/bulk density relationship. Better porosity facilitates both monomer removal and plasticiser uptake. These criteria are further enhanced when ALCOTEX WD100 is used with the ALCOTEX range of primary suspending agents. ALCOTEX WD100 is also compatible with other conventional primary suspending agents. NMR measurements have shown that ALCOTEX WD100 has a random distribution of acetate groups. The data below represents typical values obtained with different batches of ALCOTEX WD100.
