Fa'atatauga

O le UV- 329 o se fa'amautu fa'apitoa o ata e aoga i le tele o faiga fa'akomepiuta: fa'apitoa i polyesters, polyvinyl chlorides, styrenics, acrylics, polycarbonates, ma polyvinyl butyal. O le UV-329 e fa'apitoa ona ta'uta'ua mo le lautele o le fa'aogaina o le UV, lanu maualalo, maualalo le fa'aogaina, ma le solubility lelei. O fa'aoga masani e aofia ai le fa'aliliina, pepa, ma mea fa'aiila mo moli fa'amalama, fa'ailoga, gataifale ma ta'avale. Talosaga fa'apitoa mo le UV-5411 e aofia ai fa'alavalava (aemaise lava vaega o lo'o fa'apopoleina ai), mea fa'aata, fa'amaufa'ailoga, ma mea elastomeric.
