Can I store D4 PVA adhesive outside?
No. Always store away from frost in tightly closed original containers between +5°C and +35°C. PVA shouldn’t be allowed to freeze because it separates the polymer, which makes the glue useless. Poor freeze thaw ability.

Diluted PVA can also be used as a high-performance sealer, primer, bonding agent and dust proofer. Products such as Henkel Aquence DL1040 or Everbuild D4 PVA adhesives are ready mixed one component products ready for use within woodworking applications.
Will a D4 PVA adhesive discolour?
D4 PVA adhesives are white, transparent after drying and offer product stability, improved adhesion on difficult wood species (oak and larch) and no discolouration of the glue line when pressing with heat. Good quality D4 PVA adhesives are neutral pH value and thus a much lower probability of discolouration.
Is there a formaldehyde free D4 PVA adhesive?
Yes/No, you can Help protect the environment by lowering hazardous formaldehyde emissions. Lowering hazardous formaldehyde emissions with Henkel Aquence KL071/2 D3 PVA adhesive. Although this is a D3 and classed as water resistant this grade can be upgraded to D4 water durability class, according to the standard EN 204, by adding 5% of the crosslinker AQUENCE Catalyst R.397.
