    It supplies the technical description sheet of high viscosity poly aldehyde resin.

2  Summary

    The product's designation of high viscosity poly aldehyde resin is CF-A81-1，having similar performances with BASF's Laropal A-81.

    The High viscosity poly aldehyde resin is a kind of discolored saturated polymeric resin of aliphatic-aldehydes．It can be used in most paint systems，especially suitable to produce universal color pastes.

    Notes：The referenced applied domains are as follows：

                  Paint──Carpentry paint，plastic paint，cabinets paint，toy paint，

                           iron paint，gloss paint，varnish；

           Printing ink──Intaglio ink，compound ink；

                 Others──Nail polish，shoeshine，jacket oil，paper gloss paint.

    According to customers' various formulas，it can improve the gloss，tenacity，rigidity，impact resistance，adhesion，corrosion resistance，yellowing resistance and weather resistance．With this high viscosity poly aldehyde resin，it can also raise the wettability of paint and the levelling property of paint and so on possibly.

3  Recommendable directions

    First，add a measurable amount of solvent to the barrel within a high speed agitator；Second，start the high speed agitator，adding a measurable amount of high viscosity poly aldehyde resin slowly；Third，keep on mixing round until all the materiel dissolved．Then mix with other planned components according to customers' technologic conditions.

    Notes：The reference formula of universal colorants──Add the high viscosity poly

           aldehyde resin in butanone，benzene，dimethylbenzene and/or cyclohexanone （with

           50% solid content），and add toners and levelling agents，then mix up.

6  Solubility

6.1  The high viscosity poly aldehyde resin can dissolve in alcohols，ketones，esters，benzenes and other's solvents which are usually used in paint industry. Its idiographic contents in read table 2.

Table 2

    Notes：A──can be dissolved and diluted in any proportion；

           B──form suspension partially；

           C──can't be dissolved or diluted.

6.2  If adding blended solvents or heating，it can increase the dissolved speed of high viscosity poly aldehyde resin.

7  Compatibility

    The high viscosity poly aldehyde resin has favorable compatibility with most resins，binders and plasticizers．Its idiographic contents in read table 3.

Table 3

    Note：A──compatible；

          B──limited compatible；

          C──incompatible.
