Intermediate alkyd varnishes and resins

   “Khimpostavschik” produces a line of alkyd resins of various oil length modified with drying and semi-drying oils, dehydrated castor oil, styrene, acrylic oligomers, melamine-formaldehyde – and urea-formaldehyde resins of various degree of butoxylation.

   Our experts are currently working on alkyd-siloxane , alkyd-urea-formaldehyde resins. We are open to offers regarding production of new type binders you are interested in and also correction of component ratio in the formulations to meet required specifications. If requested by you we will provide test samples accompanied with basic formulas.

Intermediate alkyd varnishes and resins. Description

   Alkyd resins used as film formers in production of alkyd varnishes and pigmented paintwork materials are polyesters resulted from interaction of polyhydric alcohols with polybasic acids and their anhydrides (mainly with phthalic anhydride), modified with plant oils, etc. 

   By alcohol type  which interacts with phthalic anhydride alkyds and paintwork materials are divided into glyptalic (glycerol phthalates), pentaphthalic (pentaerythrophthalates), and etriphthalic (etriolphthalates).

By modifier used in their synthesis process alkyds are divided into: 

• alkyds modified with drying and semi-drying plant oils (linseed, sunflower oils, etc.);
  
• alkyds modified with dehydrated castor oil;
• alkyds modified with mixed plant oils and rosin;
• alkyds modified with fatty acids resulted from plant oil hydrolytic decomposition;
• alkyds modified with non-drying castor oil (modified alkyd resins);
•  alkyds modified with synthetic fatty acids, mainly C10-C16 fraction;
• alkyds modified with distilled tall oil or tall oil fatty acids;
  
• other.

   By drying property alkyds are divided into drying and non-drying.

By oil content  alkyds are divided into long oil (with oil content exceeding 60%), medium (45-59% oil) and short oil (33-44%).
 

   Alkyd resins modified with plant oils and their fatty acids are most favored as film formers.

   Various combinations of alkyd resins with other condensation and polymerization resins are also widely used. These combinations may be produced by simple mixing of two or more binder types, or result from alkyd resin modification at synthesis stage.  Such combined resins include: alkyd-urea-formaldehyde, alkyd-melamine-formaldehyde, alkyd-phenol, alkyd-epoxy, alkyd-siloxane, alkyd-urethane, alkyd-styrene, alkyd-acrylic, and others.
