RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.

Typical Selection Workflow
1
Process & Requirement Definition
Map the unit operation and define the functional, purity, and regulatory requirements the chemical input must meet.
2
Chemistry & Grade Selection
Match the solvent, intermediate, acid or base, catalyst, or specialty additive to the process and downstream compatibility.
3
Trial & Specification
Validate performance at bench or pilot scale, and set the grade, treat rate, and packaging to match throughput and handling.
4
Quality & Supply Assurance
Lock the spec with a CoA and secure multi-origin sourcing for supply resilience and consistent lot quality.

Bisphenol F diglycidyl ether (DGEBF) epoxy resin
CAS 9003-36-5
Spezialadditive
Vernetzung / Härtung
Difunctional bis-glycidyl ether of bisphenol F (the bisphenol-F analog of DGEBA, not a phenol-novolac epoxy). Its lower viscosity and improved solvent/chemical resistance suit high-solids and chemically resistant adhesives and coatings

Polyetheramine D-230
Difunctional polyether-amine curative giving epoxy systems flexibility and long pot life for adhesives and composites. (Listed by exact spine name; the spine carries no CAS for this grade, so none is asserted.)
Methylene diphenyl diisocyanate (MDI)
CAS 101-68-8
Spezialadditive
Vernetzung / Härtung
2206 (DIPHENYLMETHANE-4,4'-DIISOCYANATE) · Class
Aromatic diisocyanate that reacts with polyols to form the urethane network in PU adhesives/sealants and elastomers
Physical Description: Diphenylmethane-4,4-diisocyanate is a light yel…   Appearance: White to light yellow flakes   Odor: Odorless

Dimethyldicyane (3,3'-dimethyl-4,4'-diaminodicyclohexylmethane)
CAS 6864-37-5
Genuine cycloaliphatic diamine epoxy curing agent (commercially standard, e.g. BASF Laromin C260 class). CAS 6864-37-5 correctly resolves to 4,4'-methylenebis(2-methylcyclohexylamine); its two ring-borne primary amines crosslink epoxy resins. Cycloaliphatic diamines are specifically the class chosen for low-color, UV- and chemical-resistant epoxy casting/coating/adhesive systems, exactly the use-c
