Product Information
Melcross resins are the Amino Resins (Melamine resin) for Paint and Coatings. |
Introduction
Melcross-21 is designed as good crosslinker for most polymers which contained hydroxyl and amide groups. But there is a little limit on carboxyl groups. High methylol group derives good reactivity and water soluble properties for the coating formulations.
This resin is reduced in isobutanol and can be utilized as crosslinking agents for both solvent and water based coatings.

Indtroduction
Melcross-21 crosslinking agent is a commercial grade of methylated melamine-formaldehyde resin with a high methylol functionality content and insolved in the isobutanol solvent.
The advantages of Melcross-21 are rapid cure, higher solids enamels, gloss and gloss retention, good stability, chemical resistance in coating areas.
This resin requires only weak acid catalyst for cure at normal baking schedules. Used in both aqueous and solvent-born coatings due to excellent balance between compatibility and cure response. Showing a high tendency towards self condensation .
To control the stability, you can use tertiary amins for neutralisation and PH adjustment.
A low acid number in an alkyd or acrylic resin is sufficient. The cure reaction can be additionally catalyzed with weak organic or inorganic acids such as maleic, citric, phosphoric, or alkyl phosphoric acids, low levels of para toluene sulfonic acid catalyst. Acid catalyzed coatings may be cured as low as 100 ° C.
Melcross-21 cure similary to butylated melamine resins.
They also have a tendency to self-condense. Higher film hardness may be easily obtained by raising the level of amino crosslinking agent.
Safety
- General
Attention must be paid to the normal precautions for handling chemicals and to the measures prescript in the local health regulations. The work place must be well ventilated, skin care measures should be adapted and safety google should be worn. - Safety data sheet
P&ID Co.,Ltd. shall provide MSDS associated with MELCROSS -21 as your request. MSDS of Melcross-21
Storage
If Melcross-21 is kept in tightly closed drums or in storage tanks in the cool place, its shelf life is 12 months.
