Abordagem de solução
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.

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
