2,2-Dimethylolbutanoic acid (DMBA) o le neopentyl carboxylic acid faatasi ai ma vaega e lua o le hydroxymethyl reactive, o lea e mafai ai ona faʻaaogaina e pei o faiga faʻapipiʻi faʻavae vai ma faʻaaogaina lautele i le vai-soluble polyurethane, polyester ma le epoxy resin system.
DMBA e sili atu solubility nai loDMPAi solvents eseese, o lea e mafai ai ona faʻaleleia atili le lelei galue.
DMBA ua manatu o se tupulaga fou o lanu meamata & siosiomaga-faauo filifili extender ma emulsifier totonu mo vai-faavae polyurethane; E mafai ona faʻaaogaina i le gaosiga o mea faʻapipiʻi polyurethane aqueous e aunoa ma le faʻaogaina o solvents organic ma le ofoina atu o mea e leai ni mea e totoe. E foia ai faaletonu oDMPAe pei o le maualuga o le liusuavai, faʻagesegese le faʻamavaeina, umi le tali atu, maualuga le faʻaaogaina o le malosi, le lelei o le gaosiga o oloa, le manaʻomia o solvents organic, solvent tele residual volume ma isi.
E mafai foi ona faʻaaogaina mo le gaosiga o vai epoxy resin ma polyester adhesives.
I le taimi nei, o le fesoasoani sili lea e faʻaleleia atili (hydrophilic chain extender) o polyurethane, resins vai, faʻapipiʻi vai, vali vai ma isi mea faʻavae vai; e avea o se monomer mo le faagasologa o suiga, Dimethylolbutanoic acid ( DMBA) e le manaʻomia ni solvents (vai nai lo le vai), o le mea lea e faigofie ai le gaosiga o gaioiga ma e iai le faʻamautu ma sili ona lelei le faʻatinoga. Ae maise,DMPA(dimethylolpropionic acid) ua avea nei ma oloa sili ona lauiloa i totonu o le vai-faʻavae mo le faʻatinoina o tau!
