説明
Hydroxypropyl methacrylate(HPMA) is a clear, colorless liquid with a pungent, sweet odor. The product contains low levels of a polymerization inhibitor along with small amounts of methacrylic acid, and propylene oxide. HPMA is used in the manufacture of acrylic polymers for adhesives, inks, and coatings for automotive, appliance and metal applications. The added hydroxyl groups improve adhesion to surfaces, incorporate cross-link sites, and impart corrosion, fogging, and abrasion resistance.
化学的特性
Clear colorless liquid
使用
Monomer for acrylic resins, nonwoven fabric binders, detergent lubricating-oil additives.
主な応用
2-Hydroxypropyl Methacrylate (HPMA) used in the preparation of solid and emulsion polymers, acrylic dispersions in combination with other (meth) acrylates, which are used in various industries, especially for textile coatings and dressings. HPMA is widely used in the production of acrylic polyols for automotive components, refurbishment coatings, and industrial coatings. HPMA is also used as a comonomer in styrene-based unsaturated polyesters, PMMA-based acrylic resins, and vinyl ester formulations in anchor bolts and chemical anchors.HPMA is particularly useful as a hydrophobic hydroxy monomer in the manufacture of sealants for vacuum impregnation of cast aluminum components. HPMA is also widely used in the production of flexible UV-curable photopolymer printing plates.
一般的な説明
White liquid with a light unpleasant odor. May float or sink in water.
反応プロフィール
2-Hydroxypropyl methacrylate polymerization: May polymerize when hot or when exposed to ultraviolet light and free-radical catalysts [USCG, 1999].
健康ハザード
Inhalation causes coughing and irritation of nose and throat; lung injury may occur. Ingestion causes irritation and burning of mouth and stomach. Contact of vapor with eyes causes irritation. Liquid may cause severe eye burns and irritation of skin.
火災危険
Behavior in Fire: Compound may polymerize when hot and burst container.
安全性
2-Hydroxypropyl Methacrylate (2-HPMA) is a combustible substance. With intense healing, it forms explosive vapors with air. Vapors are heavier than air and may spread along with floors. In the case of fire, the formation of harmful gaseous products is possible. Contact with skin may cause an allergic reaction. When working with 2-Hydroxypropyl Methacrylate (2-HPMA), sanitary rules for organizing technological processes and hygienic requirements for production equipment must be strictly observed.
